如何将 SQLPlus 的 SQL 脚本附加到 bash 循环？

Question

I want to clear the table from all data ( Table_with_DB (it is in program sqldeveloper)) through sqlplus and based on filenames in the path ( path/to/files ) using SQLPlus completes the table (Table_with_DB) the filenames that are in the path.

I create 2 separate SQL files ( clear.sql ; register.sql )

and 1 with bash ( bashloop.sh )

clear.sql

BEGIN 
 package.clear('Table_with_DB'); 
END;

register.sql

BEGIN 
 package.register('folderName' , '&1);
END;

bashloop.sh

for i in path/to/files;
 do
  sqlplus -s userid/password@ @clear.sql
  sqlplus -s userid/password@ @register.sql
 done

I expect the query clear Table_with_DB and transfer the filenames from path/to/files to Table_with_DB using SQLPlus

but the actual it not work:(

Answer 1

If I understand what you want to do then in your bashloop.sh you want to replace db_name with $i - or ${i} if you have filenames with spaces.

Answer 2

Example sqlplus in loop.

#!/bin/bash

username=system
password=passwordsystem
tns_alias=esmd


for i in /opt/oracle/example1/test*/file*.txt;
 do
$ORACLE_HOME/bin/sqlplus   $username/$password@$tns_alias <<EOF
SET SERVEROUTPUT ON SIZE 2000
    BEGIN
      dbms_output.put_line('$i');
    END;
/
EOF

done;
